基于形状和纹理的外观设计专利图像检索方法

Image retrieval for a design patent based on shape features and texture features

提出一种多特征融合的外观设计专利图像检索方法。形状特征融合了几何结构特征与边界方向直方图特征来描述,通过整体结构和轮廓特征的融合全面表达了物体的形状;纹理特征融合了Gabor小波提取的特征和提出的分块统计特征;最后采用加权法融合形状特征和纹理特征,实现外观设计专利图像检索。

An image retrieval method for a design patent was proposed by means of a multi-feature fusion method.A structure and edge direction histogram described shape features of the design patent images.Texture features were obtained by Gabor wavelet and statistical characteristics of image blocks.Image retrieval for design patents was accomplished with shape features and texture features integrated with a weighted method.
